Preheat the oven to 400˚F. Line two baking trays with parchment paper.
Peel the potatoes and cut into 1/2-inch wide by 4-inch long batons. Toss in a large bowl with the oil, pepper, cumin, salt and parmesan cheese. Transfer to the lined baking trays and bake in the oven for 25 to 30 minutes, flipping the fries once halfway through cooking. Once the fries are cooked through and nicely colored on the outside, remove from the oven and enjoy while warm.
